EDWIN A. DoBB INs, OF MIDDLETOWN, NEW YORK.

LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 331,381, dated December 1, 1885. Application filed February 24, 1885. Serial No. 156,622. (No model.)

To all whom it may concern:

Be it known that I, EDWIN A. DOBBINS, of Middletown, in the county of Orange and State of New York, have-invented an Improvement in Lamp-Burners, of which the following is a specification.

In extinguishing the flame in coal-oil burners it is usual to turn the wick down; but in consequence of the volatile character of the oil and the heat of the burner a small flame will often remain at the top of the wick-tube, and the person attempting to extinguish the lamp sometimes continues to turn down the wick until the upper end passes below the wick-raiser, and the wick falls into the reservoir at the risk of an explosion.

The object of my present invention is to extinguish the flame when the wick is turned below the upper end of the wick-tube, and to prevent the ratchet being turned too far in lowering the wick; also, to operate the extinguisher automatically by the movement of the wick.

In the drawings, Figure 1 is a plan of the burner with the deflector swung back. Fig. 2 is a vertical section of the burner. Fig. 3 is an elevation of the upper part of the wicktube. Fig. 4 is a plan of the extinguisherplate as if laid out flat. Fig. 5 is an elevation of the stop-plate detached, and Fig. 6 is a section with the wick raised for lighting.

My improvements are adapted to any ordinary flat-wick burner. I.

The screw-base A, perforator air-distributer B, cone or deflector O, and chimney-springs D are represented for the purpose of illustrating an ordinary burner.

The wick-tube E and wick-raiser F are of usual construction, except that the upperpart of the wick-tube at one side is removed for the distance of about one-quarter of an inch from the top edge.

The extinguisher-plate Gis made with proj ecting pivots 'Z, passing into openings in small standards or bracket-pieces h, fastened upon the burner. The portion 9 of the extinguisher corresponds in size and shape to the opening at the side of the wick-tube E, and the pivots z are so placed that when the extinguisher occupies a nearly vertical position the portion 9 of such extinguisher fills the opening in the side of the wick -tube, and completes such the top thereof, as before mentioned. When the wick is turned down and the upper end passes below the extinguisher, the part g falls into the wick-tube and over the wick, effectually putting out the flame. The part gof the extinguisher being the heaviest or having the most leverage, causes the movement of the extinguisher upon its pivots as the wick is moved down below the portion g of the ex tinguisher. By this construction the extinguisher is made automatic, and is operated by the wick itself.

In order to prevent the ratchet or wickraiser being turned down too far, I make use of a stop-plate, L, suspended at its upper edge from the portion 9' of the extinguisher-plate. It is preferable to make use of a small wire or loop extending from the upper part of this stop-plate through an Opening in.the part 9 of the extinguisher-plate, so that said stopplate hangs and swings freely, and is raised and lowered when the extinguishenplate is swung by the action of the wick, as aforesaid. This stop-plate is of such a length that its lower edge will pass in between the teeth of the wick raising wheel or wheels and the sides of the wick-tube at the time the extinguisher falls over the end of the wick, and thereby the stop-plate will come between the teeth of the wick-raiser and the side of the wick-tube and prevent such wick-raiser being turned farther in moving the wick downwardly; hence there is no risk of the wick being turned down past the wickraiser and falling into the reservoir; but this stop-plateinterposes no obstacle to the raising of the wick.

It will be apparent by this improvement that no care is needed to be exercised in moving the wick down to extinguish the flame to retain control of it, and it is not necessary to blow down the chimney in extinguishing the a lamp. Besides this, the wick will always be moved down sufficiently below the top of the wick-tube to prevent the overflow of oil by capillary action when the lamp is not in use, thereby keeping the lamp in a much cleaner condition than is usual where the wick remains above the top of the Wick-tube. As the Wick is moved up and down the extinguisher acts to keep the upper end of the Wick even and free from incrustation, because there is a partial scraping action of the upper edge of the extinguisher against the carbonaceous incrustation at the top of the Wick, and when the wick is being raised its upper end rises against the under surface of the extinguisher and is rendered level and uniform in the act of raising such extinguisher.

I claim as my invention- 1. The combination, with the wicktube having one side near the top removed, of an extinguisher adapted to pass into the said tube, a frame forming part of the extinguisher surrounding the tube, and pivots for the frame and extinguisher, substantially as specified.

2. The combination, With the wick-tube and serrated wick-raising Wheel, of a swinging extinguisher and a stop-plate suspended from such extinguisher and passing in between the teeth of the Wick-raiser and the side of the wick-tube when the lamp is extinguished, substantially as set forth.
